Abstract
The genetic defect in a family with a mild form of Becker dystrophy was characterized by immunocytochemical, immunoblot and genomic DNA analysis in two patients and a carrier. Immunocytochemical localization on muscle preparations with a series of antibodies against different regions of the dystrophin molecule showed normal dystrophin expression with all the antibodies except anti-30 kDa antiserum. In the carrier's muscle, mosaicism was observed only with the anti-30 kDa. Immunoblot analysis revealed a band of about 250 kDa in the patients' muscles and a double band of normal and of reduced weight protein in carrier muscle. In the patients Multiplex-PCR (M-PCR) and Southern blot revealed deletions from exon 13 to exon 41. The study confirms that very mild Becker muscular dystrophy can be associated with a large intragenic deletion from the dystrophin gene.

Abstract
Different point mutations of the mitochondrial genome, which all affect the ability of mitochondria to translate their own genes and lead to partial defects of mtDNA-dependent respiratory complexes, are related to distinct clinical mitochondrial disorders. A new maternally inherited disorder, characterised by a combination of adult-onset myopathy and cardiomyopathy, with no clinical involvement of the nervous system, was found in members of a single large pedigree. A heteroplasmic new mutation was identified in the mtDNA gene specifying tRNA(Leu)(UUR). This mutation segregated specifically with the disorder, and there were significant correlations between the proportion of the mtDNA that was of the mutant form and the activities (normalised for citrate synthase activity) of the two mtDNA-dependent respiratory enzymes (complex I, r = -0.71, p less than 0.005: complex IV r = -0.77, p less than 0.005) and the maximum oxygen consumption (r = -0.82, p less than 0.005), a physiological index of aerobic metabolism. These findings strongly suggest that the tRNA(Leu)(UUR) mutation is the genetic cause of this disorder, and that lesions of mtDNA should be considered in the differential diagnosis of the hereditary cardiomyopathies.

Abstract
Immunocytochemical localization and immunoblot analysis of dystrophin in muscle fibers of 11 obligate and probable, and 7 possible carriers of Duchenne and Becker muscular dystrophy revealed an abnormal expression of the protein in 3 of them. Localization of calcium and albumin, as endogenous markers of extracellular fluid penetration, showed the presence of both molecules inside some fibers lacking dystrophin. Our morphological studies show that the initial stages leading to fiber necrosis in Duchenne muscular dystrophy are present in carriers with mosaicism. Comparison of dystrophin studies with restriction fragment length polymorphism analysis and creatine kinase levels showed that neither immunocytochemical nor immunoblot techniques for dystrophin are sensitive enough to provide a basis for genetic counseling.

Abstract
The authors have analysed the relationship between 137Cs radioactivity and pregnancy in cattle with radiometric analysis of muscle, kidney and liver of 24 cattle at various stages of pregnancy, fed with fodder exposed to radioactive fall-out. Also the relative fetal muscle, kidney, liver and myocardium have been analysed. The automatic spectra analysis and the statistical one have given the following results: there is no correlation between 137Cs retention and the pregnancy stage in the cattle sampled; the absolute 137Cs concentration is always larger in the kidney than in the muscle (Km/Mm = 1.7), while it is just minor in minor in the liver (Lm/Mm = 0.8). The fetal concentration in muscle, kidney and liver is generally homogeneous, whereas the myocardium tends to retain more 137Cs in the first stages of the pregnancy as against the other tissues. In the last stage of pregnancy it presents a lower concentration. The authors have included the fetal body weight growth to get a more realistic description of the 137Cs transfer in the mother-fetus system; this approach enables to evaluate the kinetic constants so introduced.

Abstract
Muscle hypertrophy is rare in denervating diseases. A patient with calf enlargement associated with L5-S1 radiculopathy and another with thenar, hypothenar, forearm and calf muscle hypertrophy in the course of chronic relapsing inflammatory demyelinating polyneuropathy are described. Gastrocnemius muscle biopsy revealed both type I and type II fibre hypertrophy in the former case and predominant type I fibre hypertrophy in the latter. Passive stretching and abnormal spontaneous muscular activity might have played a role in the origin of hypertrophy in both patients, but a satisfactory explanation for denervation hypertrophy has yet to be provided.

Abstract
A 23-year-old man with X-linked Becker type muscular dystrophy underwent cardiac transplantation because of dilated cardiomyopathy which was complicated by terminal heart failure. Impairment of muscle function was mild and slowly progressive, whereas the cardiac disease was severe and rapidly progressive. All four chambers of the removed heart were grossly dilated; microscopically, the myocardial fibres were hypertrophic and pale; the nuclei exhibited pleomorphism with variability in nuclear size, shape, and depth of staining.

Abstract
A 23 year-old man with x-linked Becker type muscular distrophy underwent cardiac transplantation because of dilated cardiomyopathy complicated by terminal heart failure. The muscular functional impairment was mild and slowly progressive, whereas the cardiac disease was severe and rapidly progressive. The ventricular cavities of the explanted heart were hugely dilated and the left ventricular wall thickness was moderately increased. Microscopically, a diffuse hypertrophy of the myocardial fibers and a widespread interstitial collagenous fibrosis were present. At a follow-up, two years after treatment, the patient is alive and fairly well; the degree of his muscular disability is substantially unchanged.

Abstract
To evaluate the effect of adjuvant chemotherapy in patients with local-regional nasopharyngeal carcinoma (NPC) (squamous or undifferentiated) in complete remission at the end of curative radiotherapy (RT) 229 patients were randomized from 1979 to 1983 in a multicenter study to no further therapy (116 patients) or a combination of vincristine, cyclophosphamide, and Adriamycin (doxorubicin; Adria Laboratories, Columbus, OH) (VCA) for six monthly cycles (113 patients). The RT and RT + VCA groups were well balanced for median age (50 v 49 years), histology (undifferentiated carcinoma, 73% v 70%), tumor extent (tumor limited to nasopharynx, 57% v 57%), and nodal extent (negative nodes 26% v 24%, nodes in the lower cervical levels, 17% v 16%). RT was delivered to the nasopharynx, the base of the skull, and bilateral cervical nodes using a split course technique over 10 weeks up to the dose of 60 to 70 Gy in involved sites and 50 Gy to negative nodes. Response to RT was evaluated within 65 days post-RT treatment. Analysis at 48 months did not show significant difference between the two treatment groups in terms of relapse-free survival (RT, 55.8%, RT + VCA, 57.7%, P = .45) and overall survival (RT, 67.3%, RT + VCA, 58.5%, P = .13). The pattern of relapse was similar in the two treatment arms. Distant metastases were the cause of treatment failure in about 50% of relapsing patients. Although the results of the present study did not show any benefit from VCA administered after curative RT, combined systemic chemotherapy should be further explored due to the high incidence of local and distant failure after intensive RT.

Abstract
The case of a 69-year-old woman who developed muscle weakness on chronic amiodarone treatment is reported. Muscle biopsy showed vacuolar alterations and a marked accumulation of amiodarone and of its metabolite desethylamiodarone was found in the muscle sample despite normal blood levels. Amiodarone-induced morphological alterations of the muscle may be related to the actual tissue concentration rather than to the blood level.

Abstract
We report our experience of needle biopsy over the past two and a half, viz. 395 cases. We find that the technique meets the needs of diagnosis and research very satisfactorily. We describe its advantages over open biopsy and recommend it in preference to the latter, provided that the necessary technical skill for processing the sample is available.

Over the last 14 years we have thymectomized 106 myasthenic patients, 62 by transcervical and 44 by transsternal approach. At the end of the follow-up 49 patients (46.2%) had improved, 12 of these (11.2%) being in remission. Our data supply no guidance regarding the prognosis of individual patients at the time of thymectomy. In our hands neither operation seemed to modify the natural course of myasthenia gravis.

Abstract
A 5-year-old boy with occasional pain of brief duration at the right or the left leg during exercise since the age of 4 years is reported. There was no weakness nor any other abnormality at the neurological examination. The serum creatine phosphokinase activity was elevated three times out of four. The electromyogram showed myopathic abnormalities in the biceps, it was normal in quadriceps and anterior tibial muscles. A quadriceps muscle biopsy was performed. There were no histological nor histochemical abnormalities at the routine techniques. However, a completely negative reaction with myoadenylate deaminase ( MADA ) stain was found. The MADA enzymatic activity in the muscle was very low. It is likely that the clinical syndrome is related to MADA deficiency.

Abstract
The content of 3-methylhistidine (3-MH) and 1-methylhistidine (1-MH) was measured in muscle biopsy specimens from 13 normal controls, 19 patients with Duchenne muscular dystrophy, 8 limb-girdle disease patients, and 23 disease controls with different forms of muscular pathology. 3-MH and 1-MH concentrations in normal human muscle did not appear to be influenced by sex, body weight, and age, at least for subjects in the 10--60 year age group examined. Skeletal muscle 1-MH levels did not significantly differ from mean control values in any of the pathologies investigated. In the patient population examined, the mean 3-MH level per unit of noncollagen protein (NCP) was significantly lower than normal in Duchenne dystrophy only, the reduction being related to disease severity. The significantly lower concentrations of 3-MH in muscle of Duchenne patients indicate the importance of measuring 3-MH in diseased muscle to obtain reliable estimates of the myofibrillar protein catabolic rate.

Abstract
A protocol for the evaluation of functional activities in subjects with Duchenne muscular dystrophy (DMD) was designed. The aim of our study was to define objective clinical criteria for the evaluation both of the clinical status of the patient and of the natural history of the illness itself. A protocol with such criteria is particularly necessary when testing the efficacy of treatment. 43 still-ambulant children with DMD between the ages of 3.10 yr and 10.4 yr were examined. Of this number 19 children were evaluated every 4 months over a period of 12 months; of these 14 formed part of a randomized double blind trial with L-carnitine (1.2-1.8 g/day) versus placebo.

Abstract
Four cases of acute onset myelopathy in which clinical and instrumental findings led to the diagnosis of anterior spinal artery syndrome are reported. The physiopathology, clinical medicine and treatment of vascular myelopathies are discussed on the basis of the series presented and reported data. It is also pointed out that vascular aetiology underlies a certain number of acute myelopathies, otherwise classified indiscriminately as myelitis.
